Memory Erasure and Nonvolatile Memory Parts List
The standard TDS5000 and TDS5000B Series instruments contain an open
architecture PC with an internal hard drive. TDS5000B Series instruments with
Option FHD installed have a front-panel, removable hard drive that replaces the
standard internal hard drive and the floppy drive. You can order additional
removable hard drives, Tektronix part number 065-0692-00, to swap in and out
of the instrument as needed for security reasons. This approach satisfies the
security requirements specified by the Department of Defense in DoD
5220.22--M and is recommended for TDS5000B customers with data security
concerns.
Memory Erasure
All user-storable data is stored on either the internal hard drive or the front-panel
removable hard drive. There are DOD-approved scrubbing software packages
available for the hard drive. Tektronix has no recommendations regarding the
available packages. After the hard drive has been scrubbed, the operating system
and oscilloscope software can be reinstalled using the Operating System Restore
and Product Software CDs that ship with the oscilloscope. Following reinstallation of the operating system and product software, you need to run the Signal
Path Compensation (SPC) procedure in the Utilities menu after a 20-minute
warm-up period. This returns the oscilloscope hard drive to the initial state
shipped from the factory.
Scrubbing the hard drive will not affect calibration of the instrument, since the
factory calibration constants are stored on the acquisition board, entirely separate
from any acquisition data or user files. You can completely erase or remove any
secure data without affecting the calibration of the oscilloscope. You can also
calibrate the oscilloscope in a nonsecure site, and then use the oscilloscope in a
secure area without recalibration.
Floppy disk drives are standard on TDS 5000 and TDS5000B models. Remove
all floppy disks. These can be stored or destroyed.
Most TDS5000 and TDS5000B models include read/write capable CD-ROM
drives. Remove all CDs. These can be stored or destroyed.
The following instructions give a method to disable the built-in USB and
CD-RW capability for these oscilloscopes. Using the BIOS disables the devices
for DOS programs, while the Windows Device Manager disables the devices for
Windows programs. These procedures assume the intent is to disable both USB
and the CD-RW to prevent their use.

NOTE. If you disable the USB, CD--RW, and LAN in the following procedures,
you cannot write new firmware to the hard drive. To do so, you will need to
enable one of these items.
Disable USB and CD-RW
To disable USB and CD-RW for DOS via the BIOS:
1. Press F2 during instrument Boot Up to go to the BIOS configuration menu.
2. Go to Advanced-->USB Configuration.
3. Set High-Speed USB and Legacy USB Support to Disabled.
4. Hit Esc one time to return to the main BIOS configuration menu.
5. Go to Advanced-->IDE Configuration.
6. Set IDE Controller to Primary (the CD-RW drive is in the secondary IDE
bus, and is disabled).
7. Hit Esc one time to return to the main BIOS configuration menu.
8. Go to Security--> Set Supervisor Password. Press Enter.
9. Specify a password. You will be asked to confirm the password by entering
it again. Note the password, and store it in a safe place for future use.
10. Set User Access Level to No Access.
11. Exit Saving Changes by pressing F10, and selecting OK.
To disable USB and CD-RW for Windows via the Windows Device Manager:
1. Connect a PS2 mouse and a PS2 keyboard to the oscilloscope before
powering on (because USB will be disabled).
2. Log on to the oscilloscope as an administrator.
3. Right-click on My Computer on the desktop, and select Properties.
4. Select the Hardware tab.
5. Click Device Manager.
6. Expand the Universal Serial B us controllers entry by clicking the “+” next to
it. Your screen should look similar to the following…

7. Double-click the first USB Root Hub entry.
8. Select the Power tab.
9. If the Device Description is anything other than “Generic USB Hub (5
ports)”, click the General tab, and select “Do not use this device (disable)” in
the Device Usage drop-down list.

Disable LAN Ethernet
Connectivity
NOTE. It is critical to leave the USB Root Hub show n in the above graphic
operating or the front panel of the oscilloscope will not function.
10. Click OK.
11. Repeat steps 7 through 9 for each USB Root Hub shown in the Device
Manager window.
12. Expand DVD/CD-ROM drives in the Device Manager window.
13. Right-click TEAC CD--W224A (or similar), and select Disable.
14. Reboot the oscilloscope to make the changes effective.
15. We suggest that you password protect the Windows Administrator account
and set up Guest accounts for end users so that these changes cannot be
easily reversed.
To disable LAN Ethernet Connectivity via the BIOS:
1. Press F2 during instrument Boot Up to go to the BIOS configuration menu.
2. Go to Advanced -->Peripheral Configuration.
3. Set Onboard LAN to Disabled.

4. Press Esc one time to return to the main BIOS configuration menu.
5. Press F10, and select OK to save changes and exit.
The LAN system will be disabled and no longer allow data traffic in or out.
